Hyperfunctional complement C3 promotes C5-dependent atypical hemolytic uremic syndrome in mice [PDF]

, 2019
Atypical hemolytic uremic syndrome (aHUS) is frequently associated in humans with loss-of-function mutations in complement-regulating proteins or gain-of-function mutations in complement-activating proteins.

Analysis of the Recovery of Immune Status in the Patients With Paroxysmal Nocturnal Hemoglobinuria After Treatment With C5 Complement Inhibitor

Journal of Clinical Laboratory Analysis, EarlyView.
We retrospectively evaluated the impact of C5 complement inhibition on immune cell profiles and recovery in 27 PNH patients; both CD4+ and CD8+ T cells exhibited partial recovery, while B cell counts increased but remained below normal levels. In contrast, Treg cells were significantly reduced in PNH patients and showed no notable change post‐treatment.

Erythropoietin Effect on Complement Activation in Chronic Kidney Disease

Biomedicines
The complement system is an important part of innate immunity. Despite its known protective role, the complement system may contribute to increased inflammation and tissue injury in cases where its balanced activation is disrupted.

An Open‐Label Phase 1b Study of the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of ANX005 in Patients with Huntington's Disease

Movement Disorders, EarlyView.
Complement activation is implicated in Huntington's disease; ANX005 is a potent inhibitor of component C1q. ANX005 exhibited a generally manageable safety profile with rapid reduction in C1q in the cerebrospinal fluid. Functional ability on composite Unified Huntington's Disease Rating Scale and total functional capacity was maintained, with potential ...

Complement 3a and Complement 5a as Biochemical Markers in Diabetic Nephropathy [PDF]

International Journal of Medical Arts
Background: Diabetes mellitus [DM] is growing into a global epidemic and diabetic nephropathy [DN] is one of its most feared complications. Inflammation is an important mechanism in the pathogenesis of DN and many studies have pointed to anaphylatoxins ...

Current Status of Kidney Xenotransplantation in Basic Research

Organ Medicine, EarlyView.
Kidney xenotransplantation is a potential solution to the organ shortage for end‐stage kidney disease. This review systematically elaborates on the application advances of donor pig gene editing technologies, the molecular mechanisms and regulatory strategies of xenogeneic immune rejection, and the optimization approaches of immune compatibility ...

Indoor microbial exposure increases complement component C3a and C-reactive protein concentrations in serum

Heliyon
Indoor exposure to microbial growth, caused by moisture damage, has been an established health risk for several decades. It is likely that a damp indoor environment contains biological pollutants that trigger both the innate and adaptive branches of the ...

Exploiting a novel conformational switch to control innate immunity mediated by complement protein C3a

Nature Communications, 2017
Complement C3a is an important protein in innate and adaptive immunity, but its roles in vivo are unclear. Here the authors develop novel chemical agonists and antagonists for the C3a receptor, and show that they modulate mast cell degranulation and ...

Complement in the homeostatic and ischemic brain [PDF]

, 2015
The complement system is a component of the immune system involved in both recognition and response to pathogens, and it is implicated in an increasing number of homeostatic and disease processes. It is well documented that reperfusion of ischemic tissue

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

Environmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The
